• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"c values increased\") OR (((\"ct values decrease\") OR (\"n marked decrease\"))))".
• Removing quotes may allow a broader search: (( c values increased ) OR ((( ct values decrease ) OR ( n marked decrease )))).
• Adding a wildcard symbol may retrieve word variants: (("c values increased") OR ((("ct values decrease") OR ("n marked decrease"))))*.
